So I kinda forgot how to do this *nervous laughter* um help

natali 33 [55]

1) value of x =60

2) value of x = 3

Step-by-step explanation:

We need to use cross products to solve the proportions of x.

$1.\,\, \frac{3}{5}= \frac{x}{100}$

Solving:

$\frac{3}{5}= \frac{x}{100}\\Cross\,\,multiply\,\,:\\5x=3*100\\5x=300\\x=\frac{300}{5}\\x=60$

So, value of x =60

$2.\,\,\frac{x}{8}=\frac{7.5}{20}$

$\frac{x}{8}=\frac{7.5}{20} \\20x=7.5*8\\20x=60\\x=\frac{60}{20}\\ x=3$

So, value of x = 3

What is the value of the following expression 1.8 + 0.5(y + 6) - 2 t the power of 3 when y = 14?

aalyn [17]

Answer: The answer should be 38.

I also saw that you placed a t after the -2 so I wasn't sure if it was a mistake or if it was on purpose or you left another t out of the problem on accident.

Step-by-step explanation:

2.3 (14+6) -2 to the power of three

2.3 (20) -2 to the power of three

2.3 (20) -8

46-8

I really hoped this helped and if I got it wrong with the t just reply to me c:

What is the value of x? (will give brainliest if you show your work) PLEASE HELP

andrew-mc [135]

Check the picture below.

$\bf \cfrac{8}{12}=\cfrac{x+4}{2x+1}\implies 16x+8=12x+48\implies 4x=40
\\\\\\
x=\cfrac{40}{4}\implies x=10$
